A string is stretched by a weight of 10 kg. (Take `g = 10 ms^(-2)`). The mass of one metre of string is 10 g. The velocity of transverse wave in the string is:

Options

A. `10 km s^(-1)`
B. `1 km s^(-1)`
C. `100 ms^(-1)`
D. `10 ms^(-1)`

Answer

C

Explanation

`v = sqrt(T/m) = sqrt((10 xx 10)/(10//1000)) = sqrt(10,000) = 100 m//s`
